TO ALL WIIEIOM IT MAY CONCERN: l Y y Be it known that I, ALFREDE. SMITH, of-Bronxville, Westchester county, and S/tate of New York, have :invented certain new and useful Improvements in Axles for Wagons and othervehicles; and I do hereby declare Y' s that the following is a. full description of the same. v

'The nature: of my invention consists in forming the screw-tap ofa compensating axle with a flattened .or grooved face, Aand combiningtherewith a D-vshaped washer, so` as to be carried around` Awith the axle, and thus form a bearing for the screw-nut to act against, indrawingthe hub on it, instead ofaetingA directly against the end ofthe metal box in which it runs, as is commonly the case. i v

But'to describe my invention more particularly, I rvill refer to the accompanying drawings, forming a part of the specification,- the same letters of reference, wherever they occur, referring to-like parts; t

'Figure 1 is a side view of .the axle and metal box. l Figure 2 isa longitudinal cut section of the same. Figure 3 isa detached vie\ v of the axle or spindle. v Figure 4 is a transverse vcut section of the spindle, through the line z x, lig. 2. Figure 5 is a detached view of a metal washer. A FigureG is anend view ofthe spindle.v Y Letter A is a metal box, having-.at its back end an enlarged chamber,"B, for the support of -lthe shoulder'v C of the axle, and a packing, D, for preventing the lparts fromgrinding away or cutting. out. In lthe front end ofthe metal box is-'formed an annular` collar, or diaphragm, E, for the purpose o f reducing the size of the opening in the frQnt-end'of the box. p The object of this is to form a wall, and thus make a receptacle, F, behind it, and in front of the end ot'f the spindleG, for an oil-chamber, This spindle is made of le'ss length in its bearing-surface than thelength of thejrnetal box', and has an elongated screwftapH', extending throughV the opening inthe diaphragm, to engage in the screw-nut I at thefend of the box.. Between the serew-niitand the `fune of the diaphragm, and on thelsvcrenntap, is a metal washer, J, having a section'cut out or otherwise vnotched on its inner circumference, to correspond with the flattened or. notched side or sides of 'the screw-tap, so as to vprev'ellltthe same from turning on the sc rcwltap. 'The object'of this -is to prevent the washer from rotating, andzthus, when the screw-nut is turned upthe box is'force'dup the spindle to compensa'tcfor the shrinkage or -Wearing away of the leather Washers inthe box,preventingfthcrehy the screw-nut from unloosing, when the Wheels ofthe vehicle .are backed,a s would be tho case if the nut iveredrawntightly against the end of the box, and-thc Washer not prevented from turning on thc screw-tap. It will be obvious that a cavity for the washer 'J'- may be formed intheA end ofthe nut, instead of in the end ofthe box. In either case the effect is the same, It will also be obvious thatl one or more ivnshers, J, may bc used, and leather and metal used together, and, therefore, do not restrict myself to the use ot'a single metal washer, but purposeto use one or more, and leather and metal together,l a's'circumstances may require, to accomplish the' result aimed at, to wit, making an autil rattling compensating axle for wagons and other vehicles. A N Having now described my'invention, I will proceed to set 4forthrrhat Iclaim and desire to secure by Letters Patent of the United States. 4

I claim then-shaped' washer J', in combination, with the screw-cap H' 'and diaphragm F, made and operating substantially as hereinbefore set forth. ALFRED'E. SMITH.
